To a?? z/:iom it 'may concern Be it known that I, FRANK COE, a citizen of the Fnited States, and a resident yof lValled Lake, in the county of Oakland and State of Michigan, have invented a new and Improved Sliding-Door Stop, of which thev following is a speciication.

In the use of sliding doors, as installed on barns and other outbiiildings., much annoyance is experienced because the momentum of the door, as it is shoved edgcwise in being opened, is oftenfsuflicient to cause it to run olf the end of the track. Rigid stop members or bumpers are commonly used to prevent this action, but the shock of the door against these members is very apt to cause it to jump laterally from the track. Both of these difficulties are increased in case the end of the track inclines downwardly away from the door opening, as often happens; on the other hand. when the track incliiies in the opposite direction there is a tendency for the door to slide partly or wholly shut, which. besides being of annoyance to the user, renders the door liable to be knocked view from the outside of the building showing lthe butler in position. the door being indicated in dash lines.

in engagement with the outer surface of a door.

parts throughout the several views.

In the embodiment of my invention shown in Figs. l to 8, inclusive, l indicates a base on the base plate at the end remote from f the door opening the clipV 5 having'thV Outwardly. projecting flange G. This flange is perforated to receive a bolt T that alsopasses through the slot S in an end portion 9 of a resilient door clamping plate 10 .'the"endo` which. nearest the door opening, is slottedat ll and bent atlQ to inclose the shaft 13 of a roller ll. This roller, it will be understood, is arranged to contact with the outer face lof the door and swings the resilient clamping member outwardly about its end 9; the bolt T and slot S afford means for adjusting the-door clamping plate in respect to the hase plate to accommodate doors of different thickness.

The door clamping plate is slotted at l5 and the base plate is slotted at 1T, the edges 18k of the latter being undercut as shown in Fig. 3. Mounted to slide in these slot-s is a contact or buifer plate 20 for the edge of the door: this plate has its inner end 2l of flared or dovetailed form to fit the edge of i the slot l5, and its outer end is provided with the guiding projection 23 that projects through the slot 15. The plate is normally held at tlieends of the slots nearest the roller by the coiled spring 25, one end of which is seated against the flange 6 of the clip 5; and the builer plate is prevented from tip ping by the rod 2G that is rigidly secured thereto and passes through a perforation in the flange 6 and through the slot S.

As the door slides to its open position.

it iii-st contacts with the roller ll, as stated above. whereby it is prevented from swing` ing outwardly. and its momentum is after` ward takeniip by the plate 20 and spring :25. The strength of the clamping plate 10 may 1 be made such that the roller will eXei'ta pressure on the door sulhcient to retain it iii open position; and the movement of the.

toa

clamping p'l-.ite'toward the base plate is limi' ited by the shoulders 29l on the bader plate. i'

In the modification shown in Fig. 4, the clamping plate 10 and clip 5 are replaced by a single member 30, which results in a cheaper construction.

The formation of the edges 18 on the plate 1 necessitates a machining operation that is avoided in the construction shown in Figs. 5 to 8, inclusive. In this instance the central portion of the base plate 31 is pressed up' wardly at 32 and slotted at 33; and the buffer plate 34 is notched at 35 (Fig. 8), and is provided with the vend 36 that slides inthe depression in the base plate.

As shown in Fig. 9, the roller on the resilient clamping plate may be replaced by a bend 38 that may terminate in an outwardly turned end 39. The door in this instance is preferably reinforced by a face plate 40 having a depressed bend 41 corresponding to the bend 38, and may be extended across the edge of the door at 42 as shown in Fig. 9. This insures a better retaining grip on the door than would otherwise be secured.

,but it is clear that a similar reinforcing changed considerably lwithout departing from the spirit of my invention; and it is also apparent that the device may be located in position to receive the door at the end 'of the closing movement instead of in the Iposition described. I do not, therefore, wish to .be limited otherwise than as indicated by the subjoined claims. Y
